In this particular article I've hit a bit of a wall in my understanding. The title is called 日本人の時間意識. You can probably guess what it is about from the title, but within the article the author quotes from an old book called 農業全書 by 宮崎安貞 from the 元禄 era. As a result there are a lot of grammar constructs/words I'm not familiar with.
To start with, I have no idea what the ~をも form is. For example, 「天の時にしたがひ、一寸の光陰をも大切におしみて、農業に身を投げうち、心を用ること慎でおこたること なかれ」
My rough translation is something like "Be frugal with even the smallest amount of time, give your all into agriculture and be careful not to shirk your duties." From this translation my best guess for をも is にも.
I have no idea what 天の時にしたがひ could mean. My first thought was that したがひ is some old form of 従う but it still doesn't make sense.
I'm guessing おしみて comes from 惜しむ and is just an old version of the ~て form. For example, めぐりて also shows up in 「日月の天にめぐりて瞬する間も滞りたゆみなき理りを 目当として寸陰も怠るべからず」
